ThephonologyofSesothoand those of the otherSotho–Tswana languagesare radically different from those of "older" or more "stereotypical"Bantu languages.Modern Sesotho in particular has very mixed origins (due to the influence ofDifaqanerefugees) inheriting many words andidiomsfrom non-Sotho–Tswana languages.
There are in total 39 consonantalphonemes[1](plus 2allophones) and 9 vowel phonemes (plus two close raised allophones). The consonants include a rich set ofaffricatesandpalatalandpostalveolarconsonants, as well as threeclickconsonants.
Historical sound changes
[edit]Probably the most radical sound innovation in the Sotho–Tswana languages is that theProto-Bantuprenasalized consonantshave become simple stops and affricates.[2]ThusisiZuluwords such asentabeni('on the mountain'),impuphu('flour'),ezinkulu('the big ones'),ukulanda('to fetch'),ukulamba('to become hungry'), andukuthenga('to buy') arecognatesto Sesotho[tʰɑbeŋ̩]thabeng,[pʰʊfʊ]phofo,[t͡sʼexʊlʊ]tsekgolo,[hʊlɑtʼɑ]ho lata,[hʊlɑpʼɑ]ho lapa,and[hʊʀɛkʼɑ]ho reka,respectively (with the same meanings).
This is further intensified by the law ofnasalizationand nasal homogeneity, making derived and imported words have syllabic nasals followed by homogeneous consonants, instead of prenasalized consonants.
Another important sound change in Sesotho which distinguishes it from almost all other Sotho–Tswana languages and dialects is thechain shiftfrom/x/and/k͡xʰ/to/h/and/x/(the shift of/k͡xʰ/to/x/is not yet complete).
In certain respects, however, Sesotho is more conservative than other Sotho–Tswana languages. For example, the language still retains the difference in pronunciation between/ɬ/,/t͡ɬʰ/,and/tʰ/.[3]Many other Sotho–Tswana languages have lost the fricative/ɬ/,and some Northern Sotho languages, possibly influenced byTshivenda,have also lost the lateral affricate and pronounce all three historical consonants as/tʰ/(they have also lost the distinction between/t͡ɬ/and/t/— thus, for example, speakers of the Northern Sotho language commonly called Setlokwa call their language "Setokwa" ).[4]
The existence of (lightly)ejectiveconsonants (all unvoiced unaspiratedstops) is very strange for a Bantu language and is thought to be due to Khoisan influence. These consonants occur in the Sotho–Tswana and Nguni languages (being over four times more common in Southern Africa than anywhere else in the world), and the ejective quality is strongest inisiXhosa,which has been greatly influenced by Khoisan phonology.
As with most other Bantu languages, almost all palatal and postalveolar consonants are due to some form ofpalatalizationor other related phenomena which result from a (usually palatal) approximant or vowel being "absorbed" into another consonant (with a possible subsequent nasalization).
The Southern Bantu languages have lost the Bantu distinction between long and short vowels. In Sesotho the long vowels have simply been shortened without any other effects on the syllables; while sequences of two dissimilar vowels have usually resulted in the first vowel being "absorbed" into the preceding consonant, and causing changes such as labialization and palatalization.
As with most Southern African Bantu languages, the "composite" or "secondary" vowels *e and *o have become/ɛ,e/and/ɔ,o/.These usually behave as two phonemes (conditioned byvowel harmony), although there are enough exceptions to justify the claim that they have become four separate phonemes in the Sotho–Tswana languages.
Additionally, the first-degree (or "superclose", "heavy" ) and second-degree vowels have not merged as in many other Bantu languages, resulting in a total of 9 phonemic vowels.
Almost uniquely among the Sotho–Tswana languages, Sesotho has adopted clicks.[5]There is one place of articulation,alveolar,and three manners and phonations: tenuis, aspirated, and nasalized. These most probably came with loanwords from theKhoisanandNguni languages,though they also exist in various words which don't exist in these languages and in various ideophones.
These clicks also appear in environments which are rare or non-existent in the Nguni and Khoisan languages, such as a syllabic nasal followed by a nasalized click ([ŋ̩ǃn]written⟨nnq⟩,as in[ŋ̩ǃnɑnɪ]nnqane'that other side'), a syllabic nasal followed by a tenuis click ([ŋ̩ǃ],also written⟨nq⟩,as in[sɪŋ̩ǃɑŋ̩ǃɑnɪ]senqanqane'frog'; this is not the same as the prenasalized radical click written⟨nkq⟩in the Nguni languages),[clarification needed]and a syllabic nasal followed by an aspirated click ([ŋ̩ǃʰ]written⟨nqh⟩,as in[sɪǃʰɪŋ̩ǃʰɑ]seqhenqha'hunk').
Vowels
[edit]Sesotho has a large inventory of vowels compared with many other Bantu languages. However, the ninephonemicvowels are collapsed into only five letters in theSesotho orthography.The two close vowelsiandu(sometimes called "superclose" or "first-degree" by Bantuists) are very high (with advanced tongue root) and are better approximated by French vowels than English vowels. That is especially true for/u/,which, in English, is often noticeably more front and can be transcribed as[u̟]or[ʉ]in the IPA; that is absent from Sesotho (and French).

Consonants
[edit]The Sotho–Tswana languages are peculiar among the Bantu family in that most do not have anyprenasalized consonantsand have a rather-large number of heterorganic compounds. Sesotho, uniquely among the recognised and standardised Sotho–Tswana languages, also hasclick consonants,which were acquired from Khoisan and Nguni languages.

- [d]is anallophoneof/l/,occurring only before the close vowels (/i/and/u/). Dialectical evidence shows that in the Sotho–Tswana languages/l/was originally pronounced as aretroflex flap[ɽ]before the two close vowels.
Sesotho makes a three-way distinction between lightlyejective,aspiratedandvoicedstopsin severalplaces of articulation.
| Place of articulation | IPA | Notes | Orthography | Example |
|---|---|---|---|---|
| bilabial | /pʼ/ | unaspirated:spit | p | [pʼit͡sʼɑ]pitsa('cooking pot') |
| /pʰ/ | ph | [pʰupʼut͡sʼɔ]phuputso('investigation') | ||
| /b/ | this consonant is fully voiced | b | [lɪbɪsɪ]lebese('milk') | |
| alveolar | /tʼ/ | unaspirated:stalk | t | [bʊtʼɑlɑ]botala('greenness') |
| /tʰ/ | th | [tʰɑʀʊl̩lɔ]tharollo('solution') | ||
| [d] | anallophoneof/l/,only occurring before the close vowels (/i/and/u/) | d | [muˌdimʊ]Modimo('God') | |
| velar | /kʼ/ | unaspirated:skill | k | [buˌˈikʼɑʀɑbɛlɔ]boikarabelo('responsibility') |
| /kʰ/ | fully aspirated:kill;occurring mostly in oldloanwordsfromNguni languagesand inideophones | kh | [lɪkʰɔkʰɔ]lekhokho('papbaked onto the pot') |
Sesotho possesses four simplenasal consonants.All of these can besyllabicand the syllabic velar nasal may also appear at the end of words.
| Place of articulation | IPA | Notes | Orthography | Example |
|---|---|---|---|---|
| bilabial | /m/ | m | [hʊmɑmɑʀet͡sʼɑ]homamaretsa('to glue') | |
| /m̩/ | syllabic version of the above | m | [m̩pɑ]mpa('stomach') | |
| alveolar | /n/ | n | [lɪnɑnɛˈɔ]lenaneo('programme') | |
| /n̩/ | syllabic version of the above | n | [n̩nɑ]nna('I') | |
| alveolo-palatal | /ɲ/ | a bit like Spanishel niño | ny | [hʊɲɑlɑ]honyala('to marry') |
| /ɲ̩/ | syllabic version of the above | n | [ɲ̩ɲeʊ]nnyeo('so-and-so') | |
| velar | /ŋ/ | can occur initially | ng | [lɪŋɔlɔ]lengolo('letter') |
| /ŋ̩/ | syllabic version of the above | n | [hʊŋ̩kʼɑ]honka('to take') |
The followingapproximantsoccur. All instances of/w/and/j/most probably come from original close/ʊ/,/ɪ/,/u/,and/i/vowels or Proto-Bantu *u, *i, *û, and *î (under certain circumstances).
Note that when⟨w⟩appears as part of asyllable onsetthis actually indicates that the consonant islabialized.
| Place of articulation | IPA | Notes | Orthography | Example |
|---|---|---|---|---|
| labial-velar | /w/ | w | [sɪwɑ]sewa('epidemic') | |
| lateral | /l/ | never occurs before close vowels (/i/and/u/), where it becomes[d] | l | [sɪlɛpʼɛ]selepe('axe') |
| /l̩/ | asyllabicversion of the above; note that if the sequence[l̩l]is followed by the close[i]or[u]then the second[l]is pronounced normally, not as a[d] | l | [mʊl̩lɔ]mollo('fire') | |
| palatal | /j/ | y | [hʊt͡sʼɑmɑjɑ]ho tsamaya('to walk') |
The followingfricativesoccur. The glottal fricative is often voiced between vowels, making it barely noticeable.[7]The alternative orthography used for the velar fricative is due to some loanwords from Afrikaans and ideophones which were historically pronounced with velar fricatives, distinct from the velar affricate. The voiced postalveolar affricative sometimes occurs as an alternative to the fricative.
| Place of articulation | IPA | Notes | Orthography | Example |
|---|---|---|---|---|
| labiodental | /f/ | f | [huˌfumɑnɑ]hofumana('to find') | |
| alveolar | /s/ | s | [sɪsʊtʰʊ]Sesotho | |
| postalveolar | /ʃ/ | sh | [mʊʃʷɛʃʷɛ]Moshweshwe('Moshoeshoe I') | |
| /ʒ/ | j | [mʊʒɑlɪfɑ]mojalefa('heir | ||
| lateral | /ɬ/ | hl | [hʊɬɑɬʊbɑ]hohlahloba('to examine') | |
| velar | /x/ | kg. Also⟨g⟩inGauta('Gauteng')[xɑˈutʼɑ]and someideophonessuch asgwa('of extreme whiteness')[xʷɑ] | [sɪxɔ]sekgo('spider') | |
| glottal | /h/ | h | [hʊˈɑhɑ]ho aha('to build') |
There is onetrill consonant.Originally, this was an alveolar rolled lingual, but today most individuals pronounce it at the back of the tongue, usually at the uvular position. The uvular pronunciation is largely attributed to the influence ofFrenchmissionariesatMorijainLesotho.Just like the French version, the position of this consonant is somewhat unstable and often varies even in individuals, but it generally differs from the "r" 's of most other South African language communities. The most stereotypical French-like pronunciations are found in certain rural areas of Lesotho, as well as some areas ofSoweto(where this has affected the pronunciation ofTsotsitaal).
| Place of articulation | IPA | Notes | Notes | Orthography | Example |
|---|---|---|---|---|---|
| alveolar | /r/ | can also be atap | similar to the spanishperro' | r | [ke.a u ɾata]kea orata('I love you') |
| uvular | /ʀ/ | soft Parisian-typer | r | [muˌʀiʀi]moriri('hair') |
Sesotho has a relatively large number ofaffricates.The velar affricate, which was standard in Sesotho until the early 20th century, now only occurs in some communities as an alternative to the more common velar fricative.[8]
| Place of articulation | IPA | Notes | Orthography | Example |
|---|---|---|---|---|
| alveolar | /t͡sʼ/ | ts | [hʊt͡sʼʊkʼʊt͡sʼɑ]hotsokotsa('to rinse') | |
| /t͡sʰ/ | aspirated | tsh | [hʊt͡sʰʊhɑ]hotshoha('to become frightened') | |
| lateral | /t͡ɬʼ/ | tl | [hʊt͡ɬʼɑt͡sʼɑ]hotlatsa('to fill') | |
| /t͡ɬʰ/ | occurs only as a nasalized form ofhlor as an alternative to it[3] | tlh | [t͡ɬʰɑhɔ]tlhaho('nature') | |
| postalveolar | /t͡ʃʼ/ | tj | [ɲ̩t͡ʃʼɑ]ntja('dog') | |
| /t͡ʃʰ/ | tjh | [hʊɲ̩t͡ʃʰɑfɑt͡sʼɑ]ho ntjhafatsa('to renew') | ||
| /d͡ʒ/ | this is an alternative to the fricative/ʒ/ | j | [hʊd͡ʒɑ]hoja('to eat') | |
| velar | /k͡xʰ/ | alternative to the velar fricative | kg | [k͡xʰɑlɛ]kgale('a long time ago') |
The followingclick consonantsoccur.[9]In common speech they are sometimes substituted with dental clicks. Even in standard Sesotho the nasal click is usually substituted with the tenuis click.⟨nq⟩is also used to indicate a syllabic nasal followed by an ejective click (/ŋ̩ǃkʼ/), while⟨nnq⟩is used for a syllabic nasal followed by a nasal click (/ŋ̩ǃŋ/).
| Place of articulation | IPA | Notes | Orthography | Example |
|---|---|---|---|---|
| postalveolar | /ǃkʼ/ | ejective[citation needed] | q | [hʊǃkʼɔǃkʼɑ]hoqoqa('to chat') |
| /ᵑǃ/ | nasal; this is often pronounced as an ejective click | nq | [hʊᵑǃʊsɑ]honqosa('to accuse') | |
| /ǃʰ/ | aspirated | qh | [lɪǃʰekʼu]leqheku('an elderly person') |
The following heterorganic compounds occur. They are often substituted with other consonants, although there are a few instances when some of them are phonemic and not just allophonic. These are not consideredconsonant clusters.
In non-standard speech these may be pronounced in a variety of ways.bjmay be pronounced/bj/(followed by a palatal glide) andpjmay be pronounced/pjʼ/.pjmay also sometimes be pronounced/ptʃʼ/,which may alternatively be writtenptj,though this is not to be considered standard.
| Place of articulation | IPA | Notes | Orthography | Example |
|---|---|---|---|---|
| bilabial-palatal | /pʃʼ/ | alternative tj | pj | [hʊpʃʼɑt͡ɬʼɑ]hopjatla('to cook well;) |
| /pʃʰ/ | aspirated version of the above; alternative tjh | pjh | [m̩pʃʰe]mpjhe('ostrich') | |
| /bʒ/ | alternative j | bj | [hʊbʒɑʀɑnɑ]hobjarana('to break apart') | |
| labiodental-palatal | /fʃ/ | only found inshort passivesof verbs ending with[fɑ]fa;alternative sh | fj | [hʊbɔfʃʷɑ]ho bofjwa('to be tied') |
Syllable structure
[edit]Sesotho syllables tend to beopen,with syllabic nasals and the syllabic approximantlalso allowed. Unlike almost all other Bantu languages, Sesotho does not have prenasalized consonants (NC).
- Theonsetmay be any consonant (C), alabializedconsonant (Cw), an approximant (A), or a vowel (V).
- Thenucleusmay be a vowel, a syllabic nasal (N), or the syllabicl(L).
- Nocodasare allowed.
The possible syllables are:
- Vhoetsa('to do')[hʊˈet͡sʼɑ]
- CVfi!('ideophone of sudden darkness')[fi]
- CwVhotswa('to emerge')[hʊt͡sʼʷɑ]
- AVwena('you')[wɛnɑ]
- Nnna('I')[n̩nɑ]
- Llebollo('circumcision rite')[lɪbʊl̩lɔ]
Note that heterorganic compounds count as single consonants, not consonant clusters.
Additionally, the followingphonotacticrestrictions apply:
- A consonant may not be followed by the palatal approximant/j/(i.e. C+yis not a valid onset).[10]
- Neither the labio-velar approximant/w/nor a labialized consonant may be followed by a back vowel at any time.
Syllabicloccurs only due to a vowel beingelidedbetween twol's:
- [mʊlɪlɔ]*molelo(Proto-Bantu *mu-dido) >[mʊl̩lɔ]mollo('fire') (cfSetswanamolelo,isiZuluumlilo)
- [hʊlɪlɑ]*ho lela(Proto-Bantu *-dida) >[hʊl̩lɑ]ho lla('to cry') (cfSetswanago lela,isiXhosaukulila,Tshivendau lila)
- isiZuluukuphuma('to emerge') >ukuphumelela('to succeed') > Sesotho[hʊpʰʊmɛl̩lɑ]ho phomella
There are no contrastive long vowels in Sesotho, the rule being that juxtaposed vowels form separate syllables (which may sound like long vowels with undulating tones during natural fast speech).[11]Originally there might have been a consonant between vowels which was eventually elided that prevented coalescence or other phonological processes (Proto-Bantu *g, and sometimes *j).
Other Bantu languages have rules against vowel juxtaposition, often inserting an intermediate approximant if necessary.
- Sesotho[xɑˈutʼeŋ̩]Gauteng('Gauteng') > isiXhosaErhawudeni
Phonological processes
[edit]Vowels and consonants very often influence one another resulting in predictable sound changes. Most of these changes are either vowels changing vowels, nasals changing consonants, or approximants changing consonants. The sound changes arenasalization,palatalization,alveolarization,velarization,vowelelision,vowel raising,andlabialization.Sesotho nasalization and vowel-raising are extra-strange since, unlike most processes in most languages, they actuallydecreasethesonorityof the phonemes.
Nasalization(alternatively Nasal permutation or Strengthening) is a process in Bantu languages by which, in certain circumstances, a prefixed nasal becomes assimilated to a succeeding consonant and causes changes in the form of the phone to which it is prefixed. In theSesotho languageseries of articles it is indicated by⟨N⟩.
In Sesotho it is afortitionprocess and usually occurs in the formation of class 9 and 10 nouns, in the use of theobjectival concordof the first person singular, in the use of theadjectivalandenumerative concordsof some noun classes, and in the forming of reflexive verbs (with thereflexive prefix).
Very roughly speaking, voiced consonants become devoiced and fricatives (except/x/[12]) lose their fricative quality.
Vowels and the approximant/w/get a/kʼ/in front of them[13]
- Voiced stops become ejective:
- /b/>/pʼ/
- /l/>/tʼ/
- Fricatives become aspirated:
- /f/>/pʰ/
- /ʀ/>/tʰ/
- /s/>/t͡sʰ/
- /ʃ/>/t͡ʃʰ/
- /ɬ/>/t͡ɬʰ/(except with adjectives)
- /h/becomes/x/
- /ʒ/becomes/t͡ʃʼ/
The syllabic nasal causing the change is usually dropped, except for monosyllabic stems and the first person objectival concord. Reflexive verbs don't show a nasal.
- [hʊˈɑʀbɑ]ho araba('to answer') >[kʼɑʀɑbɔ]karabo('response'),[hʊŋ̩kʼɑʀɑbɑ]ho nkaraba('to answer me'), and[huˌˈikʼɑʀɑbɑ]ho ikaraba('to answer oneself')
- [hʊfɑ]ho fa('to give') >[m̩pʰɔ]mpho('gift'),[hʊm̩pʰɑ]ho mpha('to give me'), and[huˌˈipʰɑ]ho ipha('to give oneself')
Other changes may occur due to contractions in verb derivations:
- [hʊbɔnɑ]ho bona('to see') >[hʊbon̩t͡sʰɑ]ho bontsha('to cause to see') (causative[bɔn]-bon-+[isɑ]-isa)
Nasal homogeneityconsists of two points:
- When a consonant is preceded by a (visible or invisible) nasal it will undergo nasalization, if it supports it.
- When a nasal is immediately followed by another consonant with no vowel betwixt them, the nasal will change to a nasal in the same approximate position as the following consonant, after the consonant has undergone nasal permutation. If the consonant is already a nasal then the previous nasal will simply change to the same.
Palatalizationis a process in certain Bantu languages where a consonant becomes a palatal consonant.
In Sesotho it usually occurs with the short form ofpassiveverbs and the diminutives of nouns, adjectives, and relatives.
- Labials:
- /pʼ/>/pʃʼ///t͡ʃʼ/
- /pʰ/>/pʃʰ///t͡ʃʰ/
- /b/>/bʒ///ʒ/
- /f/>/fʃ///ʃ/
- Alveolars:
- /tʼ/>/t͡ʃʼ/
- /tʰ/>/t͡ʃʰ/
- /l/>/ʒ/
- The nasals become/ɲ/:
- /n/,/m/,and/ŋ/>/ɲ/
For example:
- [hʊlɪfɑ]ho lefa('to pay') >[hʊlɪfʃʷɑ]ho lefjwa/[hʊlɪʃʷɑ]ho leshwa('to be paid')
Alveolarizationis a process whereby a consonant becomes an alveolar consonant. It occurs in noun diminutives, the diminutives ofcolour adjectives,and in the pronouns and concords of noun classes with a[di]di-or[di]di[N]-prefix. This results in either/t͡sʼ/or/t͡sʰ/.
- /pʼ/,/b/,and/l/become/t͡sʼ/
- /pʰ/,/f/,and/ʀ/become/t͡sʰ/
Examples:
- [xʷɑdi]-kgwadi('black with white spots') >[xʷɑt͡sʼɑnɑ]-kgwatsana(diminutive)
- [dikʼet͡sʼɔ t͡sʼɑhɑˈʊ]diketso tsa hao('your actions')
Other changes may occur due to phonological interactions inverbal derivatives:
- [hʊbʊt͡sʼɑ]ho botsa('to ask') >[hʊbʊt͡sʼet͡sʼɑ]ho botsetsa('to ask on behalf of') (applied[bʊt͡sʼ]-bots-+[ɛlɑ]-ela)
The alveolarization which changes Sesotho/l/to/t͡sʼ/is by far the most commonly applied phonetic process in the language. It's regularly applied in the formation of some class 8 and 10 concords and in numerous verbal derivatives.
Velarizationin Sesotho is a process whereby certain sounds become velar consonants due to the intrusion of an approximant. It occurs with verb passives, noun diminutives, the diminutives of relatives, and the formation of some class 1 and 3 prefixes.
- /m/becomes/ŋ/
- /ɲ/becomes/ŋ̩ŋ/[14]
For example:
- [hʊsɪɲɑ]ho senya('to destroy') >[hʊsɪŋ̩ŋʷɑ]ho senngwa('to be destroyed') (short passive[sɪɲ]-seny-+[wɑ]-wa)
- Class 1[mʊ]mo-+[ɑhɑ]-aha>[ŋʷɑhɑ]ngwaha('year') (cf Kiswahilimwaka;from Proto-Bantu *-jaka)
Elisionof vowels occurs in Sesotho less often than in those Bantu languages which have vowel "pre-prefixes" before the noun class prefixes (such as isiZulu), but there are still instances where it regularly and actively occurs.
There are two primary types of regular vowel elision:
- The vowels/ɪ/,/ɛ/,and/ʊ/may be removed from between two instances of/l/,thereby causing the first/l/to become syllabic. This actively occurs with verbs, and has historically occurred with some nouns.
- When forming class 1 or 3 nouns from noun stems beginning with/b/the middle/ʊ/is removed and the/b/is contracted into the/m/,resulting in[m̩m].This actively occurs with nouns derived from verbs commencing with[b]and has historically occurred with many other nouns.
For example:
- [bɑlɑ]-bala('read') >[bɑl̩lɑ]-balla(appliedverb suffix[ɛlɑ]-ela) ('read for'), and[m̩mɑdi]mmadi('person who reads')
Vowel raisingis an uncommon form ofvowel harmonywhere a non-open vowel (i.e. any vowel other than/ɑ/) is raised in position by a following vowel (in the same phonological word) at a higher position. The first variety — in which the open-mid vowels become close-mid — is commonly found in most Southern African Bantu languages (where the Proto-Bantu "mixed" vowels have separated). In the 9-vowel Sotho–Tswana languages, a much less common process also occurs where the near-close vowels become raised to a position slightly lower than the close vowels (closer to the English beat and boot than the very high Sesotho vowelsiandu) withoutATR(or, alternatively, with both [+ATR]and[+RTR]).
Mid vowel raisingis a process where/ɛ/becomes/e/and/ɔ/becomes/o/under the influence of close vowels or consonants that contain "hidden" close vowels.
- ho tsheha‡('to laugh')[hʊt͡sʰɛhɑ]>ho tshehisa‡('to cause to laugh')[hʊt͡sʰehisɑ]
- ke a bona‡('I see')[kʼɪˈɑbɔnɑ]>ke bone‡('I saw')[kʼɪbonɪ]
- ho kena‡('to enter')[hʊkʼɛnɑ]>ho kenya‡('to insert')[hʊkʼeɲɑ]
These changes are usually recursive to varying depths within the word, though, being a left spreading rule, it is often bounded by the difficulty of "foreseeing" the raising syllable:
Additionally, a right-spreading form occurs when a close-mid vowel is on the penultimate syllable (that is, the stressed syllable) and, due to some inflection or derivational process, is followed by an open-mid vowel. In this case the vowel on the final syllable is raised. This does not happen if the penultimate syllable is close (/i/or (/u/).
- -besa('roast')[besɑ]> subjunctiveke bese('so I may roast...')[kʼɪbese]
but
- -thola('find')[tʰɔlɑ]> subjunctiveke thole('so I may find...')[kʼɪtʰɔlɛ]
These vowels can occur phonemically, however, and may thus be considered to be separate phonemes:
- maele('wisdom')[mɑˈele]
- ho retla('to dismantle')[hʊʀet͡ɬʼɑ]
Close vowel raisingis a process which occurs under much less common circumstances. Near-close/ɪ/becomes[iˌ][15]and near-close/ʊ/becomes[uˌ][15]when immediately followed by a syllable containing the close vowels/i/or/u/.Unlike the mid vowel raising this processes is not iterative and is only caused directly by the close vowels (it cannot be caused by any hidden vowels or by other raised vowels).
- [hʊt͡sʰɪlɑ]ho tshela('to pass over') >[hʊt͡sʰiˌdisɑ]ho tshedisa('to comfort')
- [hʊlʊmɑ]ho loma('to itch') >[sɪluˌmi]selomi('period pains')
Since these changes are allophonic, the Sotho–Tswana languages are rarely said to have 11 vowels.
Labializationis a modification of a consonant due to the action of a bilabial/w/element which persists throughout the articulation of the consonant and is not merely a following semivowel. This labialization results in the consonant being pronounced with rounded lips[16](but, in Sesotho, with no velarization) and with attenuated high frequencies (especially noticeable with fricatives and aspirated consonants).
It may be traced to an original/ʊ/or/u/being "absorbed" into the preceding consonant when the syllable is followed by another vowel. The consonant is labialized and the transition from the labializedsyllable onsetto thenucleusvowel sounds like a bilabial semivowel (or, alternatively, like adiphthong). Unlike in languages such asChishonaandTshivenda,Sesotho labialization does not result in "whistling" of any consonants.
Almost all consonants may be labialized (indicated in the orthography by following the symbol with⟨w⟩), the exceptions being labial stops and fricatives (which becomepalatalized), the bilabial and palatal nasals (which becomevelarized), and the voiced alveolar[d]allophone of/l/(which would becomealveolarizedinstead). Additionally, syllabic nasals (wherenasalizationresults in a labialized[ŋ̩kʼ]instead) and the syllabic/l/(which is always followed by the non-syllabic/l/) are never directly labialized. Note that the unvoiced heterorganic doubled articulant fricative/fʃ/only occurs labialized (only as[fʃʷ]).
Due to the inherent bilabial semivowel, labialized consonants never appear before back vowels:
- [hʊlɑt͡sʼʷɑ]ho latswa('to taste') >[tʼɑt͡sʼɔ]tatso('flavour')
- [hʊt͡sʼʷɑ]ho tswa('to emerge') >[lɪt͡sʼɔ]letso('aderivation')
- [hʊnʷɑ]ho nwa('to drink') >[sɪnɔ]seno('a beverage')
- [hʊˈɛlɛl̩lʷɑ]ho elellwa('to realise') >[kʼɛlɛl̩lɔ]kelello('the mind')
Tonology
[edit]Sesotho is atonal languagespoken using two contrasting tones: low and high; further investigation reveals, however, that in reality it is only the high tones that are explicitly specified on the syllables in the speaker's mental lexicon, and that low tones appear when a syllable is tonally under-specified. Unlike the tonal systems of languages such asMandarin,where each syllable basically has an immutable tone, the tonal systems of theNiger–Congo languagesare much more complex in that several "tonal rules" are used to manipulate the underlying high tones before the words may be spoken, and this includes special rules ( "melodies" ) which, like grammatical or syntax rules that operate on words andmorphemes,may change the tones of specific words depending on the meaning one wishes to convey.

[edit]Theword stresssystem of Sesotho (often called "penultimate lengthening" instead, though there are certain situations where it doesn't fall on the penultimate syllable) is quite simple. Each completeSesotho wordhas exactly one main stressed syllable.
Except for the second form of the firstdemonstrative pronoun,certain formations involving certain enclitics, polysyllabic ideophones, most compounds, and a handful of other words, there is only one main stress falling on thepenult.
The stressed syllable is slightly longer and has a falling tone. Unlike in English, stress does not affect vowel quality or height.
This type of stress system occurs in most of those Eastern and Southern Bantu languages which have lost contrastive vowel length.
The second form of the first demonstrative pronoun has the stress on the final syllable. Some proclitics can leave the stress of the original word in place, causing the resultant word to have the stress at the antepenultimate syllable (or even earlier, if the enclitics are compounded). Ideophones, which tend to not obey the phonetic laws which the rest of the language abides by, may also have irregular stress.
There is even at least oneminimal pair:the adverbfela('only')[ˈfɛlɑ]has regular stress, while the conjunctivefela('but')[fɛˈlɑ](like many other conjunctives) has stress on the final syllable. This is certainly not enough evidence to justify making the claim that Sesotho is a stress accent language, though.
Because the stress falls on the penultimate syllable, Sesotho, like other Bantu languages (and unlike many closely allied Niger–Congo languages), tends to avoid monosyllabic words and often employs certain prefixes and suffixes to make the word disyllabic (such as the syllabic nasal in front of class 9 nouns with monosyllabic stems, etc.).
Notes
[edit]- ^Other authors may choose to include thelabializedconsonants as contrastive phonemes, potentially increasing the number by 26 to 75. Labialization does createminimal pairs,as is exemplified by the shortpassivesuffix, but different authors seem to be divided on whether or not these should be counted as authentic phonemes (especially since Sotho–Tswana-type labialization caused by vowel "absorption" is a fairly strange and rare process).
Besides the passives, there are still numerous minimal pairs differing only in the labialization of a single consonant (note that each of the following pairs has similar tonal patterns):
- [ʀɑlɑ]-rala('design'), versus[ʀʷɑlɑ]-rwala('carry on the head')
- [lɑlɑ]-lala('lie down' [old fashioned or poetic]), versus[lʷɑlɑ]-lwala('be sick' [old fashioned])
- [mʊʀɑ]mora('son'), versus[mʊʀʷɑ]morwa('a Khoisan person')
- [hɑmɑ]-hama('milk an animal'), versus[hʷɑmɑ]-hwama('[of fat] congeal')
- [t͡sʰɑsɑ]-tshasa('smear'), versus[t͡sʰʷɑsɑ]-tshwasa('capture prey')
- [mʊɬɑ]mohla('day'), versus[mʊɬʷɑ]mohlwa('termite')
- ^The Sotho–Tswana ejective stops/pʼ/,/tʼ/,and/kʼ/come from the Proto-Bantu *mb, *nd, and *ŋg due to the radical effects of the nasalization process. The Proto-Bantu stops *p, *t, and *k have usually become/f/,/r/,and/x/(/ʀ/and/h/in modern Sesotho) with *kû becoming[fu],and the nasalized forms of these (Proto-Bantu *mp, *nt, and *ŋk) are the two aspirated stops/pʰ/and/tʰ/,and the aspirated velar affricate/k͡xʰ/(/x/in most Sesotho speaking communities). Note that some Sotho–Tswana languages do have prenasalized consonants, or at least have less strict and varied nasalization rules, but this is almost certainly as a result of influence from neighbouring non-Sotho–Tswana languages.
- ^abStrictly speaking,/t͡ɬʰ/should be an allophone of/ɬ/found only when/ɬ/is nasalized. However, possibly due to the mixed origins of Sesotho, there are several instances of/t͡ɬʰ/appearing without nasalization (as is the case in Setswana) or of/ɬ/failing to nasalize when the nasalizing consonant is not visible (such as when forming polysyllabic class 9 nouns).
Thus one finds:
- [hʊɬɑhɑ]ho hlaha('to emerge') > class 9[t͡ɬʰɑhɔ]tlhaho('nature')
- [hʊɬɔm̩pʰɑ]ho hlompha('to respect') > class 9[ɬɔm̩pʰɔ]hlompho('respect')
- ^A further collapse occurred inSilozi— which has lost the generally unusual distinction between plain and aspirated consonants. Thus Sesotho/ɬ/,/t͡ɬʼ/,/t͡ɬʰ/,/tʼ/,and/tʰ/all map to the single Silozi phoneme/t/.
- ^Urban varieties ofPediare currently acquiring clicks as well.
- ^The IPA symbols used for the near-close vowels in this and related articles are different from those that are often used in the literature. Often, the symbols/ɨ/and/ʉ/are used instead of the standard/ɪ/and/ʊ/,but they represent theclose central unrounded voweland theclose central rounded vowel,respectively, in modern IPA.
- ^There are many historical instances in Sesotho which show an occasional confusion between the phonemes/j/,/ɦ/,and (no consonant). For example, the verb[ɑhɑ]-aha('build') often appears as[hɑhɑ]-haha(cf. Silozi-yaha), though comparison with other languages (Setswana-aga,Nguni-akha,etc.) reveals its true form. Other examples include the changing of the original verbal focus marker *-ya- to[ɑ]-a-;the second person singular objectival concord ([ʊ]-o-,but Setswana-go-and Nguni-ku-); the verb[lɑjɑ]-laya('to correct'); its Proto-Bantu form *-dag- should have given[lɑˈɑ]-laa,which does occur as a variant); verbs which end in the form[ijɑ]-iya(e.g.[sijɑ]-siya'leave behind',[dijɑ]-diya'cause to fall', etc.) being alternatively rendered as[iˈɑ]-ia;[lɪˈɪ]lee(egg; Proto-Bantu *di-gi) often appearing as[lɪhɪ]lehe;etc. It should also be noted that manyverbal derivativestreat verbs ending with[jɑ]-yaas if they end with[ɑ]-a(that is, the suffix replaces the entire[jɑ]-ya,not just the final[ɑ]-a).
- ^In Setswana and most Northern Sotho languages these are two different phonemes. The Setswana velar fricative corresponds to the Sesotho glottal fricative, and the velar affricate corresponds to the Sesotho velar fricative/affricate, but before the close vowel/u/uSetswana regularly uses the unvoiced glottal fricative.
- ^For completeness, this table uses a narrower (more detailed) transcription of clicks than usual in Bantu languages, but the rest of this article and other articles in the series use the less detailed system of click transcription. See the full consonant table above to see the usual transcriptions.
- ^Historically, in various Bantu languages, this has resulted in palatalization (giving the postalveolar and palatal consonants) and the alveolar fricative/s/.
- ^This is not to say that theglottal stopis part of the phoneme inventory of Sesotho, nor is it correct to say that the language hasdiphthongsortriphthongs(or even longer:[hɑˈʊˈɑˈiˌˈut͡ɬʼʷɑ]ha o a e utlwa'you did not hear it'). Sequences of vowels may be pronounced withhiatus(thus they are not diphthongs), but in fast speech they may simply flow into each other (thus the glottal stop is not a contrastive phoneme).
- ^Historically/x/(⟨kg⟩was an affricate[k͡xʰ](this still appears as a variation) and was therefore not an exception. Some individuals nasalize/x/and/h/to/kʰ/(possibly by analogy with the Setswanahunasalizing tokhu) and sometimes even/kʼ/(perhaps due to the unstable nature of the voiced[ɦ],which is barely audible and may cause the syllable to sound as if it does not have an onset). Though this is certainly not to be considered standard, it is an understandable reaction to the frication ( "weakening" ) of the affricate[k͡xʰ].
- ^Strangely, there are no polysyllabic verbs beginning with/j/.The verb-ya[jɑ]cannot be used with an objectival concord (it may have an intransitive, locative, or instrumentalimportand an idiomatic passive, but is not transitive) and the approximant is removed in verbal derivations. There are also no adjectives beginning with/y/or any other parts of speech which may be nasalized, so there are no instances of/j/being nasalized. Note that if a/j/were to nasalize by getting a/kʼ/in front of it, the phonotactic restrictions and phonetic rules of the language would not allow the combination */kʼj/.InSilozi,which has many verbs with word-initial/j/(many of which correspond to Sesotho vowel verbs), nasalization of/y/results in/t͡ʃ/,which has collapsed from original Sotho–Tswana/ʒ/,/t͡ʃʼ/,and/t͡ʃʰ/.Since nasalization removes voicing and frication (and Sesotho palatalization preserves aspiration), one may then deduce that if Sesotho/j/were to nasalize it would most probably become/t͡ʃʼ/tj.
- ^This second change is very strange and does not occur in most other major Sotho–Tswana languages.
- ^abThe symbols used in this and related articles for the raised allophones of the near-close vowels are non-standard, though there really aren't any standard alternatives... The difficulty lies in acknowledging the role of ATR in this process. In the past, when they were recognised at all, they were often viewed as simply an extra vowel height, and the choice of symbols differed between authors since standard IPA does not recognise the possibility of so many contrastive close vowel heights.
- ^In Sesotho, when a consonant is followed by a vowel, the shape of the lips is changed to resemble the shape of the vowel while the consonant is being pronounced (or even before, when the syllable is the first after a pause) with the shaping being more severe the higher the vowel height. Thus, when a consonant is followed by a back vowel the lips are rounded when pronouncing the consonant, and the lips are spread when pronouncing a consonant followed by a front vowel. Labialization may be explained by saying that, for some reason, the lips are rounded in anticipation of a back vowel that is never pronounced.
This also explains why labialization disappears before back vowels. Since the lips will already be rounded anyway in anticipation of the following vowel, there is no way to distinguish between a labialized consonant before a back vowel and a normal consonant before a back vowel (this is similar to the situation in English where/hw/— written as⟨wh⟩— is pronounced/h/in words such aswhom,whole,andwhore).
Note that it is also possible for labialization to simply disappear, even if any other modification of the consonant caused as a side-effect of labialization remains. One example is the tentative evolution of modern Sesotho[ɲ̩t͡ʃʼɑ]ntja('dog') from Proto-Bantu *N-bua:
- Proto-Bantu *N-bua > (nasal homogeneity) *m̩bua> (labialization) *m̩bʷa> (palatalization) *m̩pʃʷa> (loss of labialization + gaining of ejective quality) *m̩pʃʼa(as found in Northern Sotho) > (heterorganic simplification + nasal homogeneity) modern[ɲ̩t͡ʃʼɑ]
